' To all whom it mayconcern:

Be it known that we, J UgilUs PINTscH and RICHARD PINTSOH, subjects of the King of Prussia, residing at Berlin, Prussia, German Empire, have invented certain new and useful Improvements in Illuminating Apparatus,-

and we do hereby declare the following to be a full, clear, and exact description of the i11- vention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part 7 her containing the regulator.

Fig. 4 is a side view, partly in section, 'of the pipe which conducts the compressed air' from the reservoir to the regulator. -Fig. 5 is a side view, partlyin section,

This invention relates to a new apparatus for producing light from liquid hydrocarbons, and is adapted for use in floating buoys,

- light-houses, beacons; railway-cars, ships,

buildings, and other places. The principal A constituents-of the apparatus are a receptacle which contains the li quid hydrocarbon, and another receptacle containing compressed air or gas, which communicates through a pressure-regulator with the vesselcontaining the fuel and with a'lantern-having a burner. As compared with other known means of illumi= nating fioatingbuoys, for example, this ap paratus, in using the fuel in liquid form, re-

quires a much smaller fuel-reservoir than those which contain it in gaseous form; but inasmuch as the distance between the fuel-reservoir and the burner in such devices is considerably greater, in fact, than could be overcome for the elevation of the fuel by the use of capillary devices, it becomes essential that with the flame.

the column of liquid in the feedpipe that leads to the burner shall be balanced to the proper extent by artificial-meansthat is to say, held to a certain'invariable level, from which capillary devices will furtherlift it to the burner. To this end we use a chamber containing compressed air in connection with a pressureregulator in such manner that during the e11- tire operation of the apparatus the fuel in the feed-pipe of the burner will always be maintained at a certain proper level. The compressed air utilized in this process is not wasted, but is only gradually transferred in part from its own reservoir into the fuel-reservoir; hence the compressed air reservoir may also berelatively small. The burner itself is made of a certain construction so as to evaporate the fuel before it reaches contact o In the accompanying drawings we have illus- 7 trated an apparatus which is more particular 1y calculated for use on floating buoys or beacons.

Fig. 1 shows the general arrangement of parts. The vessel for containing the fuel is here shown united with that for containing the compressed air-that is to say, in the cylindrical or nearly cylindrical vessel c are securely fastened the partitions b b b ,so as to form three chambers, of which the lower one, A, serves to receive the fuel, theccntral one, B, the compressed ai r, while the upper one, 0, contains the regulator D. The upper chamber, 0, of the cylinder ais closed on top by a removable cover, 8 5 (Z, which'is more clearly shown in Fig. 2. The cylinder a, with all its attachments, is shown to be suspended from the cover of a buoy, E, and fastened to said buoy, which latter may be anchored in the usual manner. 011 this buoy is supported a framing, F, which carries a lantern, G. Forsupplying the chamber A with liquid fuel we provide a pipe, f,which may tra'iversethe chamber B, and which extends from the chamber 0 into the chamber A. \Vith-inthe chamber 0 this pipe f is closed (when theapparatus is in use) by a cover,

which is held tightly in place by a bolt and set-screw, as shown in Figs. 2 and 3, or by other means. On the partition b which di- IOO videsthe chamber 0 from ,the chamber B, stands a short pipe, 71, having a nipple, h, and

and the feeding or supply pipe or hose 1111- having a cock by means of which the connec- 1 tion between said nipple h and pipe h can at any time be interrupted or ire-established. The lower part, 71?, of the pipe h is open to the chamber B. Whenever the chamber 13 is to be charged with compressed air, a suitable hose or other pipe is coupled to the nipple h and connected with a vessel containing the compressed air. The cock in the pipe 71. is then opened, so that the compressed air may flow into the recipient l3. \Vhen the latter has been properly charged, the said cockis closed coupled from the nipple h. From the lower part, 7L2, of the pipe 71, or from any part of the cover If, extends a pipe, I, which communicates with the regulator D, which regulator may be of any well-kn own construction, and should be such as to equalize the pressure of the air or gas that passes from it to the fuel-reservoir A. The air that enters the regulator D escapes from it through a pipe, 021, (see Figs. 3 and 5,) which leads to an upright pipe, 11, that stands 011 the partition I). A suitable cock that may be opened or closed at will is contained in this pipe 01, for the same must be closed whenever the pipe 72 is opened in charging the reservoir 13; but when the apparatus is in operation the cock in the pipcn is opened. lVith the pipe a communicates and from it extends downwardly a tube, 1;, which leads through the reservoir 13 into the lower part of the reservoir A. In like manner a tube, 0, extends from the lower part of the reservoir A upward through the reservoir-.13, and thence through the chamber 0, and thence to the burner G. This tube 0 is the fuel-supply pipe for the burner; Both tubes 0 and i are at their open ends on substantially the same level as indicated in Fig. 1.

Instead of passing the tubes 0 and i through the vessels A and B in manner shown, they may also be carried alongside of said vessels, provided that their lower open ends enter the vessel A near its lower part. It is evident that whenever any pipe or pipes 0 i f traverse any one of the partitions I) If, all leakage must be prevented by careful packing.

The burner which is best adapted to this above-described apparatus is shown in Figs. (3 and 7, where the feed-pipe 0 is represented as entering an annular pipe, 1), within which the liquid fuel will be converted into gaseous fuel by heat created by the burner. From the annular pipe 1) extends a pipe, q, to the head 1- of the burner, a pointed screw, .9, regulating the amount of fuel admitted to said head. From the head 1' of the burner 6Xt-611ClllPWitl'Cl the burneutubes a 1:, which by preference stand in slightly-inclined position, as shown, and which are open at their upper ends. Above them is held by the ring tube 1) a plate, r,

having scalloped edge, as indicated in Fi 8. The flames escaping from the tubes at will heat 1 the pipe 19, and also the plate 41. The pipe 1), and also the upper part of the tubes 0 and q, are embraced by a sleeve or outer casing, 10, which serves to equalize the amount of air thatis fed to the flame and to prevent undue escape of heat from the burner, also giving greater strength to the parts thereof. The ring-pipe p is partly or wholly filled with asbestus. Fig. 7 shows itpartly filled with asbestus. I11 like manner the upper part of the tube 0 is filled with asbestus, so far, at least, as it is apt to be made very hot by the flame. Below the asbestus filling there may be a fill: ing of cotton or other capillary substance in the upper part of the tube 0. The regulator D is so adjusted that the compressed air in the vessel I3, passing through the tube i, will have a tendency to hold the liquid in the tube 0 always on a level at which the cotton or other capillary substance will dip into the liquid fuel, and thence feed it to the burner. In burning, this fuel is evaporated, and then brought to the flame in thegaseous form. Suitable contrivances may be added to the lantern to prevent violent gusts of wind from extinguishing the flame; but such is not part of the invention. I

In its main features the apparatus here de scribed is applicable to every purpose of illu mination, either for fixed or movable lights, but particularly for lighting railway-switches, railwaysignals, light -houses, ships, buoys, beacons, 8m.
